Here is the thing, I have a piece of silver jewlery that was exposed to a chemical recently (on my hand) and I woke up this morning and it had been completely transformed overnight with a black/purple/blue hue to it.
Is it tarnish? Is it toned?
If it is pretty, it's toned. If not it's tarnished. |

I'd first try to find out if it is really Silver. And if so, plated, coated or what. Next I'd worry more about my hands, than the jewlery. And we all forgot rusting and rotting. So we have Toning, Tarnishing, Corroding, Rotting, Rusting, Staining, Pitting and I'm sure there are more. All sounds like a good reason to go to plastic coins.  |

I noticed this post in trying to decide whether to purchase a Morgan dollar that exhibits (in side-by-side photos with a second, brighter coin) what appears to be a sort of bluish color. There appears to be no variation of the color on the either surface of the coin, although the reverse appears to be a somewhat lighter 'tone'. In my limited experience, I have not seen a Morgan with this appearance, and think of it as 'tarnish' rather than toning. Is this something that, e.g., PCGS would remove when restoring the coin? Thanks for any help on this. |

They were basically tax tokens and many were plastic. I have a pile of them from Missouri and from about in the 1940's to now, no tarnishing, toning, corroding, etc. They look like the day I got them. Naturally today counterfeiting them would be to easy if plastic. |

Carl ... I like to send one CCF person my new Coin Care (JPL) product. If you send me your address privately I wll send you out a bottle FREE for evaluation. Since you are always CRITICAL of most coin cleaning products. I WANT your critical evaluation. Nothing personal SAP but Australia is a killer on P&H from the U.S.. You were #2 on my list.

To the best of my knowledge (and someone with actual experience with the conservators may correct me) but I don't think they "repair" ugly tarnish. Without seeing pics it's difficult to judge, but there could well be collectors out there that would prefer your "blue" coin to an untoned example. The other concern I have with "blue" coins is the possibility of some fool having used chlorine-based bleach to attempt to induce artificial toning. Bleach forms an ugly layer of silver chloride, rather than silver sulfide, and silver chloride is notorious for not coming off without aggressive cleaning; regular anti-tarnish agents don't touch it.

They're a bit fussy about which chemicals can go through international post and how they're packaged. I've tried to order some of BadThad's magic juice a couple of times, but nobody will ship it internationally. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

You can order on ebay and use the global shipping program but shipping to AU is expensive no matter how you slice it. If you do buy using ebay, drop me a message so I know it's you and I'll include something extra to take some of the sting out of the shipping.

Sorry but giving out personal addresses over the internet is something I really avoid. Even with email, I just avoid. |

Your jewelry piece was patina'ed - it can happen naturally through the atmospheric contents or through a quicker chemical change (NNasty stuff, you really don't want to know what's in it). Tarnish is just oxidation, but more specifically it is sulfurization. The effect is more pronounced when the alloy has more copper in it.
